Description

Feedback method, feedback device and storage medium
Technical Field
The present disclosure relates to the field of communications technologies, and in particular, to a feedback method, a feedback apparatus, and a storage medium.
Background
With the development of technologies such as autonomous driving in recent years, new requirements for the performance of the V2X technology have been made in order to support new Vehicle to electrical (V2X) services. Supporting new V2x communication services and scenarios with 5G technology has been planned by 3GPP as an important content of Rel 16.
In New Radio (NR) V2X technology, a physical layer Hybrid automatic repeat request (HARQ) feedback retransmission mechanism is used for unicast and multicast services of direct communication. For unicast service, the data receiving end feeds back an Acknowledgement (ACK) when receiving data correctly (correctly decoding data), and feeds back a Negative Acknowledgement (NACK) when not receiving data correctly (decoding data is erroneous). For multicast service, two HARQ feedback retransmission methods are supported. One method is that the data receiving end feeds back NACK only when receiving an error, and otherwise does not feed back any signal. Another method is that each data receiving end feeds back ACK when receiving correctly and feeds back NACK when not receiving correctly.
The network device allocates a Physical Uplink Control Channel (PUCCH) time-frequency resource for transmitting HARQ feedback of the direct connection data to the data transmitting end through a downlink signaling. The network device may also allocate, to the data sending end through a downlink signaling, PUCCH time-frequency resources for transmitting Uplink Information such as a Physical Uplink Shared Channel (Physical Uplink Shared Channel) and downlink data (downlink) HARQ feedback, a Scheduling Request (SR), and a Channel State report (CSI). And the data sending end selects PUCCH time-frequency resources used for other uplink information different from direct connection data HARQ feedback and direct connection data HARQ feedback based on the PUCCH time-frequency resources allocated by the network equipment.
However, the PUCCH resources selected by the data transmitting end for transmitting other uplink information may coincide with the PUCCH time-frequency resources for transmitting the HARQ feedback of the direct data. When PUCCH resources for transmitting other uplink information coincide with PUCCH time-frequency resources for transmitting direct-connection data HARQ feedback, how to transmit direct-connection data HARQ feedback information is not known at present.

Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
The feedback method provided by the embodiment of the disclosure can be applied to a communication scenario of direct communication between two devices, for example, a wireless communication scenario from a vehicle to another node (V2X) for the vehicle, and the like. Wherein V represents an in-vehicle device and X represents any object interacting with the in-vehicle device. Currently X mainly contains on-board equipment, handheld devices, traffic side infrastructure and networks. The information mode of the V2X interaction comprises the following steps: vehicle-to-Vehicle (V2V), vehicle-to-road (V2I), vehicle-to-person (V2P), and Vehicle-to-Network (V2N). In the present disclosure, the communication scenario for direct communication between two devices may also be a terminal-to-terminal (D2D) communication scenario. The devices that perform direct communication in the embodiments of the present disclosure may include various handheld devices, vehicle-mounted devices, wearable devices, computing devices or other processing devices connected to a wireless modem, which have wireless communication functions, as well as various forms of User Equipment (UE), mobile Stations (MS), terminals (Terminal), terminal Equipment (Terminal Equipment), and so on. For convenience of description, the following scenario of performing direct communication between vehicle-mounted devices is described as an example in the embodiments of the present disclosure, where the vehicle-mounted devices performing direct communication include a vehicle-mounted device serving as a data sending end and a vehicle-mounted device serving as a data receiving end.
Fig. 1 is a schematic view of a scenario in which communication is directly performed between vehicle-mounted devices, and a network device configures various transmission parameters for data transmission for the vehicle-mounted device 1. The vehicle-mounted device 1 serves as a data sending end, the vehicle-mounted device 2 serves as a data receiving end, and the two devices are in direct communication. The link for communication between the network device and the vehicle-mounted device is an uplink link and a downlink link, and the link between the vehicle-mounted device and the vehicle-mounted device is a direct link (sidelink). In a Cellular-Vehicle wireless communication technology (C-V2X), communication between a Vehicle-mounted device and other devices can be transferred through a base station and a core network, that is, uplink and downlink between a terminal device and the base station in an original Cellular network are used for communication; or directly through a direct link between devices. Compared with Uu interface communication, sidelink communication has the characteristics of short time delay, low cost and the like, and is very suitable for direct communication between vehicle-mounted equipment and other peripheral equipment with close geographic positions.
The V2x sidelink communication in Long Term Evolution (LTE) can only support some Basic V2x applications in security, such as voice broadcast communication of Basic Security Messages (BSM), for example, exchange Cooperative Awareness Messages (CAM) or Distributed Environment Notification Messages (DENM). With the recent development of technologies such as automatic driving, new requirements for the performance of V2x technology are put forward in order to support new V2x services. The support of new V2x communication services and scenarios using 5G NR technology has been planned by 3GPP as an important part of Rel 16. The 3gpp SA1 (Service Requirement) working group has established some new business requirements that V2x communication needs to meet, including fleet management (Vehicles platform), extended Sensors (Extended Sensors), advanced Driving (Advanced Driving), and remote Driving (remote Driving). Overall, NR V2x sidelink is required to provide higher communication rate, shorter communication delay, and more reliable communication quality.
For unicast and multicast services of direct connection communication, a direct connection physical layer Hybrid automatic repeat request (HARQ) feedback retransmission mechanism is supported. For unicast service, the data receiving end feeds back an Acknowledgement (ACK) when receiving data correctly (correctly decoding data), and feeds back a Negative Acknowledgement (NACK) when not receiving data correctly (decoding data is erroneous). For multicast service, two HARQ feedback retransmission methods are supported. One method is that the data receiving end feeds back NACK only when receiving an error, and otherwise does not feed back any signal. Another method is that each data receiving end feeds back ACK when correctly receiving and feeds back NACK when incorrectly receiving.
In the related art, NR V2x supports a Mode (Mode) 1 resource allocation method. The network device may allocate time-frequency resources to a terminal serving as a data sending end through the downlink signaling. And the terminal serving as the data sending end sends the direct connection control information and the direct connection data by using the allocated time frequency resources. According to different specific downlink signaling time-frequency resource allocation methods, the method can be further divided into the following three types:
type1 configured grant: the network device sends time-frequency Resource information to the terminal through a semi-static downlink signaling (e.g., radio Resource Control (RRC) signaling), and configures a set of periodic time-frequency resources for direct connection Control/data transmission for the terminal.
Type2 configured grant: the network equipment sends a semi-static downlink signaling to a terminal to configure periodic time-frequency resources for direct connection transmission; however, the base station sends Downlink Control Information (DCI) to the terminal according to the specific size and position of the time-frequency resource in each period.
C. Dynamic resource allocation: and the network equipment allocates time frequency resources to the terminal for direct connection transmission by transmitting the DCI.
When the terminal uses the mode1 resource allocation method, the terminal serving as a data sending end is supported to transmit the HARQ feedback information of the direct connection data to the network device through a Physical Uplink Control Channel (PUCCH). For a Type2 configured grant or a dynamically scheduled time-frequency resource allocation mode, the selection and configuration of the PUCCH for transmitting the HARQ feedback information of the direct connection data may reuse the selection and configuration mechanism of the PUCCH for transmitting the downlink data HARQ, but the PUCCH resource for transmitting the HARQ feedback information of the direct connection data and the PUCCH resource for transmitting the downlink data HARQ may be configured separately.
For the configuration of PUCCH resources for direct data HARQ, the terminal is configured with up to 4 sets of PUCCH resources (for convenience of description, the sets of PUCCH resources configured for direct data HARQ are referred to as direct data HARQ PUCCH resources in the embodiments of the present disclosure). Each of the downlink data HARQ PUCCH resources corresponds to a different load size of the direct connection data HARQ feedback. When the direct connection data HARQ selects the PUCCH for transmission, one group of PUCCH resources are selected from the first resource set according to the load size of the direct connection data HARQ, and then one PUCCH in the selected group of PUCCH is selected for transmission of the direct connection data HARQ according to the Type2 configured grant or the indication in the DCI of the dynamic scheduling.
When PUCCH resources for transmitting downlink data HARQ are configured, the terminal may be configured with at most 4 additional sets of PUCCH resources (for convenience of description, multiple sets of PUCCH resources configured for downlink data are referred to as downlink data HARQ PUCCH resources in the embodiment of the present disclosure). Each group of directly connected data HARQ PUCCH resources corresponds to different Uplink Control Information (UCI) load sizes. When downlink data HARQ selects downlink data HARQ PUCCH resources for transmission, firstly a group of downlink data HARQ PUCCH resources are selected according to the load size of the downlink data HARQ, and then one of the selected downlink data HARQ PUCCH resources is selected according to the indication in DCI for scheduling downlink data transmission.
In addition, when a PUCCH resource selected by downlink data HARQ and a PUCCH transmitting other UCI (Scheduling Request (SR) or Channel State Information (CSI)) are overlapped in time domain, downlink data HARQ and other UCI are combined and transmitted on one PUCCH. The method for selecting the PUCCH also comprises the steps of firstly selecting a group of PUCCH resources according to the load size of the combined UCI, and then selecting one PUCCH resource in the group of PUCCH resources according to the indication in the DCI for scheduling downlink data transmission.
By adopting the above resource allocation manner, a situation that PUCCH resources selected for the direct-connection data HARQ and PUCCH resources selected for other uplink Information different from the direct-connection data HARQ overlap in a time domain may occur, for example, the other uplink Information may be downlink data HARQ feedback Information, scheduling Request (SR), channel State Information (CSI), or uplink data. In this case, how to transmit the direct connection feedback information (direct connection data HARQ) is a problem to be solved.
The embodiment of the disclosure provides a feedback method, wherein when a PUCCH resource for transmitting direct connection feedback information and a PUCCH resource for transmitting other uplink information coincide in a time domain, one of the PUCCH for transmitting the direct connection feedback information and the PUCCH for transmitting the other uplink information is selected.
In the present disclosure, a PUCCH used for transmitting direct connection feedback information is referred to as a first PUCCH, and a physical uplink channel used for transmitting other uplink information other than the direct connection feedback information is referred to as a second physical uplink channel. In an embodiment, the second Physical Uplink Channel may be a PUCCH, or a Physical Uplink Shared Channel (PUSCH), and when a first PUCCH resource for transmitting the direct connection feedback information and a second Physical Uplink Channel resource for transmitting other Uplink information overlap in a time domain, the first PUCCH or the second Physical Uplink Channel is transmitted.
In one embodiment, when a first PUCCH resource for transmitting direct connection feedback information and a second physical uplink channel resource for transmitting other uplink information overlap in a time domain, the first PUCCH is transmitted and transmission of the second physical uplink channel is discarded, or the second physical uplink channel is transmitted and the first PUCCH is discarded.
Fig. 2 is a flowchart illustrating a feedback method according to an exemplary embodiment, where the feedback method is used in a terminal, as shown in fig. 2, and includes the following steps.
In step S11, it is determined that a first PUCCH resource for transmitting direct connection feedback information and a second physical uplink channel resource for transmitting other uplink information overlap in a time domain.
In the embodiment of the present disclosure, the direct connection feedback information may be direct connection data HARQ feedback information. The other uplink information refers to other uplink information except the direct data HARQ feedback information, and may be uplink control information or uplink data information, for example, the other uplink information may be downlink data HARQ feedback information, SR, CSI report, or uplink data. When the other uplink information is uplink control information, the second physical uplink channel may be a second PUCCH. When the other uplink information is uplink data information, the second physical uplink channel may be a PUSCH.
In step S12, a first PUCCH corresponding to the direct connection feedback information is transmitted, or a second physical uplink channel corresponding to other uplink information is transmitted. In the embodiment of the present disclosure, when PUCCH resources for transmitting direct connection feedback information and physical uplink channel resources for transmitting other uplink information coincide in a time domain, the first PUCCH is transmitted without transmitting the second physical uplink channel, or the second physical uplink channel is transmitted without transmitting the first PUCCH, so that uplink information can be transmitted with a small change to an uplink transmission signaling. And the network equipment does not need to change the signaling, and the uplink data is received according to the original data transmission mode.
It is understood that the first PUCCH resource or the second physical uplink channel resource that is not transmitted in the embodiment of the present disclosure may be discarded.
The following describes the above-mentioned related process of transmitting the first PUCCH without transmitting the second physical uplink channel, or transmitting the second physical uplink channel without transmitting the first PUCCH, with reference to practical applications.
In one embodiment, in this embodiment of the present disclosure, it may be determined to transmit the first PUCCH or transmit the second physical uplink channel according to the configuration information.

And the configuration information is used for identifying the first PUCCH when the first PUCCH is transmitted. And when the configuration information is used for identifying the transmission of the second physical uplink channel, transmitting the second physical uplink channel.
The configuration information related in the embodiments of the present disclosure may be configuration information stored in the terminal, or configuration information received from other communication devices, which is not limited in all embodiments of the present disclosure.
For example, the direct connection feedback information is direct connection data HARQ, the other Uplink information is Uplink Control Information (UCI), and the second physical Uplink channel is a second PUCCH.
When the terminal determines that the PUCCH used for transmitting UCI and the PUCCH selected by the direct connection data HARQ coincide in time domain, when the configuration information identification carries out uplink transmission on the UCI and does not transmit the direct connection data HARQ, the terminal determines to transmit a second PUCCH. When the terminal determines that the PUCCH used for transmitting UCI and the PUCCH selected by the direct connection data HARQ coincide in time domain, when the configuration information identification carries out uplink transmission on the direct connection data HARQ, the terminal determines to transmit the first PUCCH.
For another example, the direct connection feedback information is direct connection data HARQ, other uplink information is uplink data, and the second physical uplink channel is PUSCH.

And if the priority of the direct connection data transmission is higher than that of the downlink data transmission, transmitting the first PUCCH and giving up the second PUCCH transmission, namely transmitting the HARQ feedback of the direct connection data without transmitting the transmission of the UCI.
For another example, the direct connection feedback information is direct connection data HARQ, and the second physical uplink channel is PUSCH.
